Roxy Jacenko shares her mum's reaction to her "affair" while her husband was in jail.

Roxy Jacenko has recalled the moment she confessed to doing “something really, really stupid” to her mother Doreen Davis.

And according to the Daily Mail, that really stupid thing was kissing her ex-boyfriend Nabil Gazal – and being photographed – last April while her husband Oliver Curtis was in jail.

The 38-year-old has previously spoken about her regrets at having a relationship with Gazal while her husband, and father of her two children Pixie, six, and Hunter, four, served time for insider trading.

In August, Jacenko told News Corp the affair came about because she “didn’t think there was any hope” for their five-year-marriage.

“My marriage in my eyes had come to an end … it had been a seriously tough 12 months,” she said. “We were drunk and stupid and mucking around.”

“I’d spoken to a lawyer about divorce, and [Curtis] knew that. I told him I wasn’t sure what was going to happen in the future … it was without question the worst 12 months of my life.”

On Wednesday, at her In Conversation With Roxy Jacenko event in Sydney, the businesswoman spoke of “pushing boundaries”, recalling when she had to face the consequences of doing so, the Daily Mail reports.

“It’s important to stay relevant – to stay relevant you have to keep pushing the boundaries and I have perhaps pushed the boundaries a little too much,” Roxy said, before reportedly drawing on her affair with Gazal.

“I remember vividly walking up to my mother’s apartment which is about eight stairs from my apartment and saying to her: ‘f**k me, I’m in trouble,’ because I had done something really really stupid.”

“I just remember my mother’s face, I literally could’ve picked her jaw up from the floor.”

Roxy told the audience that she has accepted her mistake.

“I’ve pushed every f**king boundary in the book – everyone has read about it. But I think I have to take the good with the bad.’

“I think everyone makes mistakes – mine are documented.”
